Abstract

The utility model discloses an LED (Light-emitting Diode) bulb lamp which comprises a lamp cap, a lamp body support, a plastic mounting barrel, four light-transmitting lampshades, LED light sources, four substrates for mounting the LED light sources, and an LED driver, wherein the four light-transmitting lampshades are circumferentially and uniformly distributed; a circumferential gap is formed between every two adjacent light-transmitting lampshades; each light-transmitting lampshade is connected with a groove-shaped reflector made of a metal material correspondingly, and spliced with the corresponding groove-shaped reflector to form a sealing space; each groove-shaped reflector in each sealing space comprises a bottom plate and two side wing plates; planes where every two side wing plates are located are mutually perpendicular; a ventilation gap is formed between the side wing plates in every two adjacent sealing spaces; one substrate is mounted on the bottom plate of each sealing space correspondingly; viewed from the cross section perpendicular to a central axis of the lamp cap, directions of the front surfaces of the four substrates are staggered by 90 degrees sequentially; and the LED light sources are mounted on the four substrates respectively. Light rays of the LED bulb lamp can be uniformly irradiated around, and a heat-dissipation effect is good.

Description

The LED bulb lamp

Technical field

The utility model belongs to the technical field of LED light fixture, is specifically related to a kind of LED bulb lamp.

Background technology

The LED light fixture is the new type light source of a kind of efficient, energy-saving and environmental protection, safety, but during the work of the led light source of LED light fixture, 20～30% the power of only having an appointment is converted into luminous energy, all the other power of 70～80% are converted into heat energy, and the degree of heat is quite high, therefore these heats are effectively distributed rapidly, otherwise can influence LED light fixture operate as normal, the aggravation light decay, also may make the glow color of LED light fixture undesired at reduction of service life.

LED shot-light and LED bulb lamp all are more common LED light fixtures.Wherein, the designing requirement of LED shot-light is that light can compare directive the place ahead, concentrated area, and the designing requirement of LED bulb lamp then is light as far as possible equably around the directive, and the profile of LED bulb lamp must be similar to traditional incandescent globe as far as possible.In addition, in order to prevent dust deposit on the led light source assembly of LED bulb lamp, must utilize sphere or hemispherical lampshade that the led light source assembly is sealed.

The requirement of above-mentioned several respects makes the heat dissipation problem of the LED bulb lamp more complicated that becomes, specific as follows: in order to strengthen the radiating effect of LED bulb lamp, people naturally expect setting up the metal heat sink of many fins, as shown in Figure 1, but because the profile of LED bulb lamp must be similar to traditional incandescent globe as far as possible, therefore metal heat sink 9 can not be arranged in lampshade around, metal heat sink can only be arranged on the rear of lampshade, as shown in Figure 1, like this, can bring following problem: led light source 4 can only be arranged on the substrate vertical with central axis 41, be that the front of led light source is towards the place ahead, but not towards around, like this, the light around the directive just a little less than.Certainly, the market also has partial L ED bulb lamp, and they do not adopt the metal heat sink of many fins, the led light source that therefore is enclosed in lampshade inside can be arranged as towards around, but obviously, the radiating effect of this LED bulb lamp is very poor.

The utility model content

The purpose of this utility model is to overcome above-mentioned shortcoming and provides and a kind of LED bulb lamp, and its light is evenly around the directive, and good heat dissipation effect.

Its purpose can realize by following scheme: a kind of LED bulb lamp, comprise lamp holder, lamp body bearing, plastic mounting tube, transparent lamp shade, led light source, be used for installing substrate, the led driver of led light source, lamp holder is connected the rear of plastic mounting tube, the lamp body bearing is connected the place ahead of plastic mounting tube, led driver is installed in the plastic mounting tube, it is characterized in that described transparent lamp shade upwards is set as four in week even the branch, it is 80 that the cross section of each sheet transparent lamp shade is radian ^O-85 ^OCircular arc, be formed with circular gap between adjacent two transparent lamp shades; Each sheet transparent lamp shade correspondence is connected with the flute profile reflector that metal material is made, form a seal cavity after the flute profile reflector amalgamation of each sheet transparent lamp shade and correspondence, the flute profile reflector of each seal cavity includes a base plate and wing plates on two sides, and plane, wing plates on two sides place is orthogonal; Be formed with ventilation gaps between the side wing of adjacent two seal cavities; The quantity of described substrate is four, and each piece substrate correspondence is installed on the base plate of a seal cavity; From the cross section perpendicular to the lamp holder central axis, the front of four substrates is towards staggering 90 successively ^O, described led light source is installed in respectively on four substrates; Described transparent lamp shade and flute profile reflector are fixedly mounted on the place ahead of lamp body bearing, at the rear of transparent lamp shade and flute profile reflector small fan are installed also, and the installation direction of small fan is towards transparent lamp shade and flute profile reflector.

The utlity model has following advantage and effect:

1, the utility model disperses led light source to be sealed in four seal cavities, both satisfied the sealing demand of led light source, make the led light source assembly heat can mutual superposition again, and can be from the outer surface heat radiation of each seal cavity, the area of dissipation of each seal cavity is big, the surface that had both comprised transparent lamp shade, the surface that more comprises metal flute profile reflector, and be formed with ventilation gaps between the side wing of adjacent two flute profile reflectors, fan can be by the heat radiation of drying of this ventilation gaps, therefore good heat dissipation effect guarantees the led light source operate as normal, increases the service life.

2, the utility model is installed in led light source respectively on four substrates, and the front of four substrates is towards staggering 90 successively ^O, the led light source back also has the flute profile reflector, thus the light that sends of led light source can directive around, and after the reflection of flute profile reflector, the light around the directive is more even.
