Description

Light projector

Technical Field

The utility model relates to a projecting lamp.

Background

The projector is a lamp that specifies that the illuminance on the illuminated surface is higher than that in the surrounding environment. Also known as spotlights. In general, it can be aimed in any direction and has a structure that is not affected by the climatic conditions. The method is mainly used for large-area operation field mines, building outlines, stadiums, overpasses, monuments, parks, flower beds and the like. Thus, almost all large area lighting fixtures used outdoors can be considered as floodlights. The emergent beam angle of the projection lamp is wide and narrow, the variation range is between 0 and 180 degrees, and the beam is particularly narrow and is called a searchlight.

However, the existing projection lamp is poor in heat dissipation effect, easily causes the failure of the LED lamp panel, and reduces the practicability of the projection lamp.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a projecting lamp that the radiating effect is good, simple structure.

The purpose of the utility model is realized like this:

a projection lamp comprises a light-transmitting surface cover, a light-gathering cover, an LED lamp panel, a back shell and a bracket, wherein heat dissipation holes are formed in the back shell at intervals, the back surface of the back shell is inwards recessed corresponding to the position of the LED lamp panel, metal grid strips are arranged at intervals at the recessed positions, through holes are formed between the metal grid strips and the metal grid strips, heat conduction columns are arranged at the through holes, one ends of the heat conduction columns extend into the inner cavity of the back shell, the other ends of the heat conduction columns extend outwards, and lead holes convenient for cables to penetrate through are formed in the bottom wall of the back shell;

the LED lamp plate is fixed at the backshell inner chamber, the snoot is opened there is light trap, and the snoot is fixed in the backshell, and LED lamp plate card is put in light trap department, printing opacity face lid is fixed on the backshell and is sealed the backshell inner chamber, bracket and backshell are connected, and the up bearing light that passes through of bracket, the light that the LED lamp plate produced jets out towards printing opacity face lid under the effect of snoot.

The LED lamp plate is fixed on the backshell, and the backshell interval is opened there is the louvre, and the backshell corresponds LED lamp plate position sunken inwards moreover, and the depressed part is provided with metal grid strip and heat conduction post, the heat that LED lamp plate working process produced sees through louvre, metal grid strip and heat conduction post and derives outwards to improve the radiating effect who passes through the lamp, thereby prolong the life of projecting lamp.

The purpose of the utility model can also adopt the following technical measures to solve:

furthermore, the bracket is U-shaped, and the dorsal scale is connected with the U-shaped bracket both ends with the rotation mode respectively, and the bracket uses the junction to rotate 180 degrees as rotation center.

The bracket can rotate by 180 degrees, and the user can place the projection lamp at any angle, so that the requirements of the user are met.

Furthermore, damping silica gel is arranged at the joint of the end part of the U-shaped bracket and the back shell.

The junction is provided with damping silica gel, and after the angle of illumination of projecting lamp had been adjusted to the user, because damping silica gel hinders the bracket and puts to make the projecting lamp maintain the angle of illumination that the user set for and shine.

Further, the heat conduction column is a ceramic column body. The ceramic heat conduction effect is good, and the heat that the LED lamp plate produced is outwards derived through pottery, and the radiating effect is good.

The utility model has the advantages as follows:

the utility model discloses, the LED lamp plate is fixed on the backshell, and the backshell interval division has the louvre, and the backshell corresponds LED lamp plate position sunken inwards moreover, and the depressed part is provided with metal grid strip and heat conduction post, the heat that LED lamp plate working process produced sees through louvre, metal grid strip and heat conduction post and derives outwards to improve the radiating effect who passes through the lamp, thereby prolong the life of projecting lamp.

The utility model discloses, the bracket can 180 degrees rotations, and the projecting lamp can be put to the angle wantonly to the user, satisfies user's demand, moreover the junction is provided with damping silica gel, and after the user adjusted the angle of illumination of projecting lamp, because damping silica gel hinders the bracket and puts to make the projecting lamp maintain the angle of illumination that the user set for and shine.

Detailed Description

The invention will be further described with reference to the following drawings and examples:

in the embodiment, as shown in fig. 1 to 6, a projector includes a light-transmitting surface cover 1, a light-gathering cover 2, an LED lamp panel 3, a back shell 4 and a bracket 5, where heat dissipation holes 41 are formed at intervals in the back shell 4, the back surface of the back shell 4 is recessed inward corresponding to the LED lamp panel 3, metal grid bars 42 are arranged at intervals in the recessed portions, through holes 43 are formed between the metal grid bars 42 and the metal grid bars 42, heat conduction columns 44 are arranged at the through holes 43, one ends of the heat conduction columns 44 extend into an inner cavity of the back shell 4, the other ends of the heat conduction columns 44 extend outward, and lead holes 45 through which cables can pass are formed in the bottom wall of the back shell 4;

LED lamp plate 3 is fixed at the 4 inner chambers of backshells, condenser cover 2 is opened there is light trap 21, and condenser cover 2 is fixed in backshell 4, and the card of LED lamp plate 3 is put in light trap 21 department, printing opacity face lid 1 is fixed on backshell 4 and is sealed the 4 inner chambers of backshells, and the light that LED lamp plate 3 produced jets out towards printing opacity face lid 1 under the effect of condenser cover 2.

Bracket 5 is U type bracket 5, and the dorsal scale 4 is connected with the rotation mode respectively at U type bracket 5 both ends, the tip of U type bracket 5 and the junction of dorsal scale 4 are provided with damping silica gel 51, and bracket 5 uses the junction to rotate 180 degrees as the rotation center.

The heat-conducting column 44 is a ceramic cylinder. The ceramic heat conduction effect is good, and the heat that LED lamp plate 3 produced is outwards derived through pottery, and the radiating effect is good.

LED lamp plate 3 is fixed on

backshell

4, and 4 spaced apart on the backshell have louvre 41, and backshell 4 corresponds LED lamp plate 3 positions inwards sunken moreover, and the depressed part is provided with metal grid strip 42 and heat conduction post 44, the heat that 3 course of operation of LED lamp plate produced sees through louvre 41, metal grid strip 42 and heat conduction post 44 and exports 4 outwards to improve the radiating effect who passes through the lamp, thereby prolong the life of projecting lamp.
