Background technology
The heat radiation lamp socket generally comprises the radiating fin in the pedestal and the outside, and pedestal is placed luminescence unit) (as the LED illuminator) and circuit board, the lead of circuit board passes pedestal and is connected with external power source.Like this, when luminescence unit is luminous, can be used as light source uses, but, because its luminescence unit is the illuminator of high brightness, therefore, also can produce high heat when it is luminous, this high heat can't distribute fast at the radiating fin of existing structure, thereby causes luminescence unit and circuit board overheated and damage, and influences the service life of luminescence unit and circuit board.
The utility model content
The purpose of this utility model is to provide a kind of heat radiation lamp socket, and this heat radiation lamp socket can increase area of dissipation, improves radiating efficiency, prolongs luminescence unit and circuit board service life.
The utility model provides a kind of LED pixel lamp again, and its radiating effect is good, and can rationally regulate distribution of light, and dismounting is also very convenient.
The utility model is realized by following approach.
A kind of heat radiation lamp socket, the radiator structure that it comprises a solid column and is located at this column outside; Radiator structure comprises that some radiating fins and connector constitute, and this radiating fin axially is provided with along solid column body structure outer surface; Connector is a loop configuration, is connected with described radiating fin is terminal, and both constitute a plurality of heat dissipation channels with draft effect in the solid column body structure outside.
Further, described solid column end face is provided with for the groove that luminescence unit is installed.
Have the through hole that supply lines wears in the described solid column.
Have, described radiating fin and connector are structure as a whole again.
Described solid column external surface is distributed with the rib of some projectioies.
Described connector outer surface is distributed with the rib of some projectioies.
A kind of LED pixel lamp of the present utility model, the circuit connecting parts and the heat radiation lamp socket that comprise led chip, wiring board, connection external power, wherein, described heat radiation lamp socket one solid column and the radiator structure of being located at this column outside, this radiator structure comprises some radiating fins and connector; Described solid column end face is provided with groove; Described radiating fin axially is provided with along solid column body structure outer surface, and connector is a loop configuration, is connected with described radiating fin is terminal, and both constitute a plurality of heat dissipation channels with draft effect in the solid column body structure outside; Described led chip and wiring board are installed in the groove of heat radiation lamp socket, and the top of led chip is provided with lens, and these lens cooperate with the heat radiation lamp socket and are tightly connected.
Again, described circuit connecting parts is the contact conductor of drawing from heat radiation lamp socket bottom.
Described circuit connecting parts is screw-type, bayonet coupling or push-in type elastic interface.
In addition, radiating fin described in the utility model and connector are structure as a whole.
The utility model has following advantage compared to prior art:
Heat radiation lamp socket of the present utility model, form a plurality of heat dissipation channels in the external side of solid column with draft effect, compare with existing radiator structure, not only increased conduction and swept area, and, because the effect of heat dissipation channel, also make column outside external environment condition can produce the air-flow of convection current, thereby the heat that luminescence unit such as LED is produced is discharged rapidly by heat loss through convection, further accelerates distributing of heat.
The LED pixel lamp that uses this heat radiation lamp socket to make (calls pixel to the minimum component units of LED display, component units as the LED illuminating lamp, can be similar the notion of introducing LED pixel lamp), because its heat radiation lamp socket better heat radiating effect, make also improve greatly the service life of LED pixel lamp, and the lens on the pixel lamp can carry out rational layout to the distribution of light.In addition, because this pixel lamp and external power supply adopt contact conductor or screw-type, bayonet coupling or push-in type elastic interface, make dismounting very convenient.
